Reverting to File Test Settings
Reverting to File Test Settings
The application allows you to revert the test settings parameters values to
the file original values. The retrieved values are IOR, backscatter, Helix
factor, splice loss threshold, reflectance threshold, end-of-fiber threshold
and fiber core size. The result values are automatically updated to reflect
the change.
Note: You can revert to file test settings for multiple files only if the FR2-FC option
is activated.
Note: You cannot use this feature when you open a competitor’s .SOR files and
iOLM generated .SOR files.
To revert to file test settings:
1. On the Files tab select the OTDR files you want to modify.
2. From the Summary tab, click the Revert to File Test Settings button,
then confirm your choice.
